AWS Serverless Common Mistakes – Costs (4/7)

This article, part 4 of a 7-part series on AWS serverless mistakes, focuses on cost management. It explains why serverless costs are hard to estimate, warns of self-inflicted Denial-of-Service (DoS) via recursive calls, and details how DDoS attacks can lead to billing spikes. It provides practical advice on setting Lambda concurrency limits, timeouts, and API Gateway throttling to control costs, and compares expenses across Lambda, CloudWatch, and databases.
